Yesterday I took a series of photos and videos that were there last night, but today when I went to upload them to my computer they simply weren't there! I did not delete them - what happened to them??? Is this a problem with the iphone? I have never ever before had this happen on any phone I have had in the past. I can't believe that they can just disappear? It makes the phone totally unreliable - how do you know how long they will even stay on the phone in order to have time to sync them?? I am utterly gobsmacked that they can just disappear???
